<html>
<head></head>
<body>
<form id="Form1" method="post" runat="server">
<asp:Button id="Button1" runat="server" Text="Button" onClick="Button1_Click">
</asp:Button>
</form>
</body>
</html><script language="c#" runat="server">
void Page_Load(Object Src, EventArgs E)
{
Button1.Attributes.Add("onclick", "return confirm('Are you sure you wish to delete this item?');");
}
void Button1_Click(Object Src, EventArgs E)
{
Response.Write("Button1_Click");
}
</script>Button1按钮同时相应客户端的javascript指令和服务器端的Button1_Click事件。
Response.Write("<script>window.alert('你想干什么');</script>");
alert的用法楼上很多了,我就不说了
Response.Write("<script defer>window.alert('你想干什么');</script>");
这样弹出的窗口不会出现白屏，而且能夺取焦点啊
public void MessageBox(string strText ,Page objPage)
{
/* 1、编写：
* 2、功能：在客户端弹出对话框
* 3、参数：string strText 对话框的文本信息；Page objPage 对话框的所在页面
* 4、返回值： 无
* 5、用途：提示用户操作是否合法，应如何进行下一步操作
*/
string IidScript,strWindow;
strWindow="window.alert('"+strText+"')";
IidScript = "<script>"+strWindow+"</script>";
objPage.RegisterClientScriptBlock("failure",IidScript);
}//调用事例
//MessageBox("提示内容",Page)//其中Page是永远不变的。
一、直接输出代码：
response.write("<script>window.alert('这是一个对话框!');</script>");
二、注册一个脚本到客户端：
registerclientscript("Message","<script>window.alert('这是一个对话框!');</script>");
三、注册一个控件的html属性，在执行服务器控件之前执行一段客户端脚本：
button btn = new button();
btn.attributes["onClick"]="confirm('您确定吗？');";
请问，可以放在CodeBehind里面吗？
还有就是麻烦一下大家给我讲解一下客户端脚本，和服务器端脚本的区别
